Hi Frustrated Mattress Shopper,
The short version is that you would need the density of all the polyfoam layers for me to make any meaningful comments but I would tend to avoid any mattress where there are 2" or more of lower quality or unknown foams.
If I’m reading your specs right the first mattress (left hand side specs) includes (from the top down) …
1" super soft foam
1" high density foam
1" gel 3.5#
1" firm foam
This is 3" of unknown quality polyfoam (most likely lower quality/density) and an inch of memory foam that is in the lower quality range. I would avoid this unless you can confirm that all the polyfoam is high quality in which case I would consider only an inch of lower quality memory foam to be acceptable.
The second mattress (right hand side specs) includes …
1 1/8" convoluted memory foam
1" super soft foam
1" gel 5.0#
1.75" firm brick foam
This is almost 4" of unknown quality/density polyfoam and 1" of good quality memory foam. I would avoid this as well unless once again you can confirm that the polyfoam has no more than an inch or so of low quality materials (which is unlikely).
These are both mattresses I would tend to avoid.
Some of the better options or possibilities I’m aware of in the Kansas City area are listed in post #2 here.
